V Application filed September 19, 1921. Serial No. 501,601.

To all whom it may concern:

Be it known that I, JOHN Q. SHERMAN, a citizen of the United States, and a resident of Dayton, in the county of Montgomery 6 and State of Ohio, have invented certain new and useful Improvements in Manifolding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to manifolding machines wherein the object is to feed a plurality of webs over a writing table or platen in sections 'of adjustable length.

In former applications for patent, viz Serial No. 433,208 and Serial No. 436,774, filed Dec. 27, 1920, and Jan. 12, 1921. I have described various devices for the purpose of frictionally feeding paper webs in lengths 30 which are optionally controlled by varying the arc of contact of the friction feeding members. Also in application filed by me Serial N 0. 443,009, filed February 7 1921, I have described a method of feed of manifolding paper by means of radially moving pins, which are thrust into holes in the paper by cam devices of fixed position and ad justable length.

In the patent to Schirmer No. 940,481, dated November 16, 1909, is shown and described the so-called pin wheel method of paper feed wherein wheels carrying radial pins are used to feed and align a number of webs of paper with marginal holes :15 therein, said webs being held loosely in the machine while the feed is going on so as to permit self-adjustment of the webs.

My present invention involves a diiferent principle from those set forth in the first set of applications above referred to, in that it relates to pin wheel methods of feed of paper, one of the modifications relating to the radially moving pin structure, secondly above referred to.

rovide a device by means of which ad'ustable length strips can be fed but in w ich the true alignment feed of the Schirmer The object of the present invention is toadjustable working periphery devices which effect the said separation.

I. accomplish my object by that certain construction and arrangement of parts to be hereinafter more specifically pointed. on and claimed.

1n the drawings, 1

Figure 1 is a side elevation showing one form of adjustable pin wheel feed, in which the entire pin wheel devices are thrust downwardly away from the paper.

F gure 2 is a side elevational detail of a radial moving pin feeding device, in which the pm operating cam devices are thrust downwardly, so as not to thrust the pins into paper engagement.

Figure 3 is a side elevation of a still simpler form in which the adjustment operates on the writing table itself to lift the paper from the pins.

Figure 4 is a detail elevation of the feed inhibiting device of Figure 3 shown at right angles to the showing in said former figure.

Figure 5 is a view of the feed inhibiting devices of Figure 1 in edgewise elevation.

Figure 6 is a detail of the paper guiding roll common to all of the modifications. I indicate at 1 the side frames of all of the modifications, and at 2 the main writing table portion over which the webs of paper are to pass. I also indicate by a common reference numeral the main feed shafts 3 in all views, and the paper guide rollers 4. This construction is that of the Schirmer patent referred to, except for the particular mounting of the feed shafts. The adjustable members for each modification are the same also and comprise segmentshaped plates having journals on the feed shaft.

Thus in each case there is a fixed segment plate 5 having its collar 6 pinned to the feed shaft. There is also another segment plate 7 having a like periphery journaled loosely over the feed shaft alongside of the first named plate. These segment devices are like those shown in my applications, Serial No. 433,208 and No. 436,774.

revolve may be positioned alongside of the fixed plate, sothat but a short are is represented by the combined peripheries, but it may be moved into other positions radially of the feed shaft to form desired extensions of the are of the fixed piece. In order to The lo'osely journaled plate being free toretain the movable plate in adjusted position a in 8 is set into its face, which pin passes t rough an arcuate slot 9 in the fixed plate. The pin has a threaded end on which is a suitable clamp nut 10.

In Fi res 2 and 3 the up er or guide roller 4 15 mounted as in the chirmer patent, above referred to, with springs above the spindles of the rolls to hold them down in proper position of abutment on contact 'wheels 11 mounted on the feed shafts.

In Figure 1 the roller 4 is mounted between a pair of arms 12 on a cross rod 13 set into the machine frame and spring-ener- 1g'ized at 14. The arms 12 or one of them as a nose 15 at the end which may be engaged by a latch 16 to hold the roller upwardly and out of the way when installing paper in the machine. The arms 12 may also carry a tear-off lmife when desired.

In the simplest form of device, as shown in Figure 3, the writing table is hinged at 17 in any usual manner familiar in the manifolding machine art, and carries on its underside directly over the feed shaft and in line with the segment device a roller 18 in a simple bracket 19. Where the segment late devices are duplicated the rollers may duplicated, but a single adjustable segment device and one roller will suflice to accomplish my purpose.

The feed of the paper is accomplished by one or more pin wheels 20 on the feed shaft. The pins 21 on these wheels pass through slots in the writing table and engage successive holes in the paper. The contact Wheels 11 extend through slots in the table also.

When the segment device comes into contact with the roller 18, it lifts the writing table and thus forces it upwardly so as to strip" the paper ofl? the pins and the guide roller off the cams.

The guide roller will then be clamped tightly against the writing table and the paper held against any movement until the table is dropped again, whereupon the next pin of the pin wheelto come into juxtaposition with the paper web holes will pick up the feeding where it left off.

In this construction it will be a simple matter to arrange the timing of the initial lifting motion and the duration of the lift together with the movement of the pins, so that the pa er will come down again over the pins w ich have moved around and come to a stop in about the exact position in which it was lifted. It will be noted that the handle of the feed shaft will come to the end of its motion and be latched, as is common practice in manifolding machines, at just the point where the lifting action of the segment devices comes to an en Referring next to Figure 1, it will be observed that the feed shaft is mounted on :1

housing or journal box 30, at each end, these boxes being set into slideways 3.1 on the side frames.

The journal boxes are pressed upwardly by springs 32 mounted beneath them as shown and the pin wheels 20 on the shaft, as well as the cams or contact wheels 11 for the guide roller 4, are held up into operating position by means of the springs. At their uppermost positions the journal blocks come into contact with stops 33.

The segment or segments in this instance contact with a roller or rollers 34 on a cross bar 35 set beneath the Writing table, and force the entire feed shaft down, so as to withdraw the pin wheels and permit the guide roller to come down and clamp the paper.

In the showing'in Figure 2- additional reference being hereby made to my application, berial No. 443,005) the pins 40 are carried in a set of wheels having outer rims 41 in which the pins slide, and inner rims 42 serving as a spring abutment and through which the reduced ends 475 of the pins will slide. The pins have springs 44 thereon, which are secured to the ends thereof and bear against this innerrim. A pair of cams 45 are provided and mounted on resiliently supported pieces 46, which are set into slideways 47. The slideways are supported by rods 48 in the sides of the machine.

When held up normally by the springs 48 these pieces 46 hold the cams in position to contact with the ends of the pins and force them radially into a position of engagement with holes in the paper. When forced down against the spring action the pieces remove the cams, so that the pins do not rise into engagement but are kept out of same by the springs thereon.

The segments in this instance contact with rollers set on a cross bar 49 connecting the two pieces 46.

It will be noted that all the modifications have the same common features of a pin feed and an adjustable inhibiting device which effects a separation of the pins and the paper.

The last described modification might be better operated with a clamp to engage the aper when the pins are out of engagement,

ut as I have shown such a clamp in my copending application Serial No. 452,185, filed March 14, 1921, I do not believe it to be necessary to go into further details in this case, particularly as in the claims that follow I do not specifically claim this one of the modifications.

I do not desire it to be resumed that my invention is intended to e limited to the three modifications shown, because of the fact that I have not mentioned others.
